Bug 395409 – virtual/dev-manager-0: emerge --depclean tries to unmerge sys-fs/udev when sys-apps/busybox[mdev] is installed

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Grzegorz {NineX} Krzystek 2011-12-20 20:50:03 UTC]

emerge --depclean
!!! 'sys-fs/udev' (virtual/dev-manager) is part of your system profile.
!!! Unmerging it may be damaging to your system.

after udev unmerge system can't boot anymore due no static dev files in my system

Reproducible: Always

Actual Results:  
emerge -n sys-fs/udev (add to world file) fixes problem

[Comment 1 Zac Medico 2011-12-20 20:55:10 UTC]

The virtual/dev-manager dependencies look like this:

 || ( sys-fs/udev sys-fs/devfsd sys-fs/static-dev sys-freebsd/freebsd-sbin )

Do you have another one of those installed, such as sys-fs/devfsd or sys-fs/static-dev? If so, then this behavior is expected.

sys-apps/busybox-1.19.0 have IUSE="... +mdev"

added -mdev my USE reemerged busybox, that solved problem
look at #395319

[Comment 4 Zac Medico 2011-12-20 22:51:08 UTC]

Since portage behaves as it's supposed to, given the sys-apps/busybox[mdev] choice in virtual/dev-manager (bug #395319), this bug belongs to base-system since they maintain the virtual.

[Comment 5 Ben Kohler 2011-12-20 23:07:46 UTC]

This is big.  Current stable systems all have udev eligible for depclean right now.

[Comment 6 SpanKY 2011-12-20 23:49:54 UTC]

i've dropped IUSE=+mdev for all busybox ebuilds, and moved udev to first in the ||() list in the dev-manager virtual

otherwise, if a user has manually built busybox with USE=mdev, then it does satisfy the virtual/dev-manager dependency which means udev could be removed

whether the user wants that behavior is up to them
